Definitions
- the present invention relates to methods for treating cystitis and in particular acute cystitis, to compositions for use in these therapies.
- Urinary tract infections are common and may be dangerous. The clinical presentation and severity varies, depending on the site of infection and molecular basis of disease.
- APN acute pyelonephritis
- bacteria ascend into the renal pelvis, where they cause an intense mucosal inflammatory response with progression into the renal parenchyma. Symptoms include high fever, malaise, loin pain as well as poor feeding and irritability in infants.
- acute cystitis infection is localized to the urinary bladder, resulting in dysuria, frequency and supra-pubic pain, typically without systemic involvement. While the clinical entities of acute pyelonephritis and acute cystitis typically are quite distinct, the molecular determinants of clinical presentation and severity are largely unknown.
- a pathogen-specific TLR4 response is activated by P fimbriated E . coli, through ceramide release and the successive phosphorylation of the TICAM-1 (TRIF) and TICAM-2 (TRAM) adaptors, CREB-1, c-FOS and c-JUN activates IRF- and AP1- dependent transcription. Additional involvement of MyD88, TIRAP and NF-kB depends on the virulence repertoire of the infecting strain. Genetic studies in the murine UTI model have identified IRF3-dependent gene expression and mCXCR2-dependent neutrophil activation as determinants of bacterial clearance and tissue homeostasis.
- Acute uncomplicated cystitis is characterized by localized inflammation and symptoms from the lower urinary tract, typically dysuria and urgency and frequency of urination. It occurs predominantly in girls and healthy women with normal urinary tracts and at least 60% of all females will report an episode during their lifetime. The recurrence rate is high, especially in a subset of patients, where recurrent cystitis episodes may cause chronic tissue damage and impact the quality of life.
- acute cystitis patents pose a highly significant challenge to the health care system.
- the urinary bladder mucosa is often under microbial attack but does not always retaliate with such force, as in acute cystitis.
- the epithelium remains fairly unresponsive, despite bacterial numbers well above 10 5 CFU/ml (9, 10). It is therefore challenging to understand, at the molecular level, how a state of exaggerated inflammation can be generated specifically in acute cystitis patients. Interactions of bladder cells with pathogenic bacteria have been shown to trigger an innate immune response, involving the epithelium and adjacent mucosal cells, such as mast cells and macrophages.
- Uroepithelial cells from women with recurrent cystitis have an increased density of receptors for adhering bacteria and bacterial persistence in intracellular communities has been studied as a reservoir of infection, but the molecular basis of susceptibility and disease has remained unclear.
- Il-1b - / - mice were protected from pathology, as were Casp1 - / - mice which have an IL-1 ⁇ secretion deficiency.
- Asc - / - and Nlrp3 - / - mice which are deficient for inflammasome constituents, developed an IL-1 ⁇ hyperactivation state with rapid, fulminant bladder inflammation and tissue damage, accompanied by massive neutrophil infiltration and upregulation of inflammasome genes. Mutations in these ASC or NLRP-3 genes in humans may therefore provide an indicator of susceptibility to disease, and also provide a prophylactic or therapeutic strategy for addressing disease.
- the applicants have also identified a new mechanism of IL-1 ⁇ processing which is responsible for this phenotype, involving the metalloproteinase MMP-7 in MMP-7 dependent processing and MMP-7 overexpression, in the bladder mucosa.
- the MMP-7 response may be explained by a direct effect of ASC and NLPR-3 on the MMP7 promoter, resulting in de-repression of Mmp7 expression in Asc - / - and Nlrp3 - / - mice.
- the present invention provides a method for treating cystitis comprising administering to a patient in need thereof, an effective amount of a reagent selected from the group consisting of IL-1 ⁇ inhibitors and MMP inhibitors.
- the reagent is an IL-1 ⁇ inhibitor, and many such compounds are known in the art. These include for example, small molecules such as anthraquinones, described for example in USP 4,244,968 including diacerein, as well as proteins and peptides such as interleukin-1 receptor antagonist (IL-1 RA) for example anakinra, and rilonacept, or pharmaceutically acceptable salts thereof, or prodrugs thereof, and combinations of these.
- the reagent is an IL-1 ⁇ receptor antagonist, such as anakinra ( US Patent No 5,075,222 ).
- the reagent is an MMP inhibitor, and in particular an MMP7 inhibitor.
- MMP inhibitors are known as described for example Durrant et al. Chem. Biol. Drug Des 20111; 78; 191-198 , the content of which is incorporated herein by reference.
- Particular examples include batimastat, periostat (doxycycline hyclate), marimastat, or salts or prodrugs thereof, but in particular batimastat.
- the invention further provides a reagent selected from the group consisting of IL-1 ⁇ inhibitors and MMP inhibitors for use in the treatment of cystitis, in particular acute cystitis.
- a reagent selected from the group consisting of IL-1 ⁇ inhibitors and MMP inhibitors for use in the treatment of cystitis, in particular acute cystitis.
- Particular reagents are as described above.
- the invention further provides a method for diagnosing cystitis and in particular, acute cystitis, said method comprising detecting elevated levels of IL-1 ⁇ or MMP-7 in urine of a subject. Suitable detection methods are known in the art, and include ELISA.
- the invention provides a method for diagnosing susceptibility to cystitis, said method comprising detecting a mutation in a gene encoding a protein selected from ASC or NLRP-3 which results in downregulation of said gene and/or in the expression of inactive protein.
- a mutation in a gene encoding a protein selected from ASC or NLRP-3 which results in downregulation of said gene and/or in the expression of inactive protein.
- Diagnosis may be carried out at the gene level, whereby the sequence of the Asc and/or Nlrp-3 is completely or partially determined and compared with a normal gene. For example, sites of common mutations that leads to inactivation or downregulation of the ASC or NLRP-3 proteins may be analyzed and the presence or absence of the selected mutation may be used to assess the likelihood that the patient is susceptible to cystitis.
- diagnosis may be carried out at the protein level, where a suitable sample from a subject, such as a blood, serum, plasma or urine sample is analyzed for the presence of active ASC or NLRP-3 protein.
- suitable methods in this case may include immunochemical assays such as ELISAs which use antibodies specific for the target proteins.
- the invention provides a method for preventing or treating cystitis in a patient susceptible thereto as a result of a mutation which impacts on the expression of functional ASC or NLRP-3, which method comprises administering to said patient a protein selected from ASC or NLRP-3 or a functional fragment or variant thereof.
- fragment' refers to a peptide or protein which lacks one or more amino acids found in a full length protein but which still has the function of the full length protein.
- the expression 'variant' refers to a peptide sequence in which the amino acid sequence differs from the basic protein or peptide sequence in that one or more amino acids within the sequence are substituted for other amino acids.
- the variant produces a biological effect which is similar to that of the basic sequence.
- Amino acid substitutions may be regarded as "conservative" where an amino acid is replaced with a different amino acid in the same class with broadly similar properties.
- Non-conservative substitutions are where amino acids are replaced with amino acids of a different type or class.
- Amino acid classes are defined as follows: Class Amino acid examples Nonpolar: A, V, L, I, P, M, F, W Uncharged polar: G, S, T, C, Y, N, Q Acidic: D, E Basic: K, R, H.
- altering the primary structure of a peptide by a conservative substitution may not significantly alter the activity of that peptide because the side-chain of the amino acid which is inserted into the sequence may be able to form similar bonds and contacts as the side chain of the amino acid which has been substituted out. This is so even when the substitution is in a region which is critical in determining the peptide's conformation.
- Non-conservative substitutions may also be possible provided that these do not interrupt the function of the protein or peptide.
- variants will have amino acid sequences that will be at least 70%, for instance at least 71%, 75%, 79%, 81%, 84%, 87%, 90%, 93% or 96% identical to the basic sequence.
- Identity in this context may be determined using the BLASTP computer program with the basic native protein sequence as the base sequence.
- the BLAST software is publicly available at http://blast.ncbi.nlm.nih.gov/Blast.cgi (accessible on 12 March 2009).
- Variants may also include addition sequences such as tag sequences that may be used for instance in facilitating purification of the peptide or in detection of it.
- the variant may further comprise an affinity tag such as chitin binding protein (CBP), maltose binding protein (MBP), glutathione-S-transferase (GST), FLAG, myc, biotin or a poly(His) tag as are known in the art.
- CBP chitin binding protein
- MBP maltose binding protein
- GST glutathione-S-transferase
- FLAG FLAG
- myc myc
- biotin biotin
- poly(His) tag as are known in the art.
- the variant may comprise a fluorescent protein such as green fluorescent protein (GFP).
- the invention provides a protein selected from ASC or NLRP-3 or a functional fragment or variant thereof, for use in the treatment of patients suffering from or susceptible to cystitis as a result of a mutation which impacts on the expression of functional ASC or NLRP-3 respectively.
- the reagent or protein is suitably administered in the form of a pharmaceutical composition, which further comprise a pharmaceutically acceptable carrier.
- a pharmaceutical composition which further comprise a pharmaceutically acceptable carrier.
- Such compositions are known in the art.
- Suitable pharmaceutical compositions will be in either solid or liquid form. They may be adapted for administration by any convenient route, such as parenteral, oral or topical administration or for administration by inhalation or insufflation.
- the pharmaceutical acceptable carrier may include diluents or excipients which are physiologically tolerable and compatible with the active ingredient.
- compositions are prepared for injection, for example either subcutaneously or intravenously. They may be liquid solutions or suspensions, or they may be in the form of a solid that is suitable for solution in, or suspension in, liquid prior to injection. Suitable diluents and excipients are, for example, water, saline, dextrose, glycerol, or the like, and combinations thereof. In addition, if desired the compositions may contain minor amounts of auxiliary substances such as wetting or emulsifying agents, stabilizing or pH-buffering agents, and the like.
- Oral formulations will be in the form of solids or liquids, and may be solutions, syrups, suspensions, tablets, pills, capsules, sustained-release formulations, or powders.
- Oral formulations include such normally employed excipients as, for example, pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, sodium saccharin, cellulose, magnesium carbonate, and the like.
- Topical formulations will generally take the form of suppositories or intranasal aerosols.
- traditional binders and excipients may include, for example, polyalkylene glycols or triglycerides; such suppositories may be formed from mixtures containing the active ingredient.
- the amount of reagent administered will vary depending upon factors such as the nature of the reagent being used, the size and health of the patient, the nature of the condition being treated etc. in accordance with normal clinical practice. Typically, a dosage in the range of from 1 ⁇ g-50mg/Kg for instance from 2-20 mg/Kg, such as from 5-15 mg/Kg would be expected to produce a suitable effect.
- the urinary bladder mucosa is often under microbial attack but rarely retaliates with full force.
- the epithelium remains refractory despite bacterial numbers well above 10 5 CFU/ml.
- bacteria that cause acute cystitis create a state of exaggerated inflammation and the patients develop the characteristic symptoms of dysuria, frequency and pain.
- IL-1b as a crucial host sensor of bladder infection and inflammasome dysregulation as a cause of bladder pathology.
- IL-1b the metalloproteinase MMP-7 is introduced as a new molecular player in mucosal inflammation, proteolytically cleaving IL-1b.
- the importance of IL-1b and MMP-7 is proven by treatment of susceptible mice with IL-1RA or MMP inhibitor. Elevated IL-1b levels were also detected in patients with acute cystitis compared to patients with ABU. This molecular basis of acute cystitis also provides as a new therapeutic approach using IL-1b and MMP-7 inhibitors as immune-modulators of acute cystitis.
- IL-1b is a potent pro-inflammatory cytokine that initiates and amplifies innate immune responses. IL-1b production increases in response to viral, bacterial, fungal and parasitic infections and IL-1b is essential for the defense against microbial attack. IL-1b responses may also be detrimental, however, and dysregulation of IL-1b has been observed in autoimmune and auto-inflammatory disorders, such as rheumatoid arthritis, multiple sclerosis, Crohn's disease or neuro-degenerative disorders. This dichotomy was apparent also in the present study, where a controlled IL-1b response accompanied the clearance of infection in WT mice.
- the NLRP-3 inflammasome is activated by a number of microbial stimuli including LPS, MDP, bacterial RNA, poly(I:C) as well as ATP and bacterial pore-forming toxins.
- NLRP-3 activation stimulates the binding of ASC through homotypic pyrin domains and the caspase recruitment domain of ASC serves as an adaptor that binds NLRP-3 to pro-Caspase-1 to form the inflammasome.
- the dramatic disease phenotype in Asc - / - and Nlrp3 - / - mice strongly suggested that a functional inflammasome response is required to maintain tissue homeostasis in infected bladders.
- Cystitis strains that were active IL-1b inducers also increased the expression of NLRP-3, ASC and Caspase-1 in human bladder cells and processing of IL-1b was detected, with secretion of the mature form into urine and cell supernatants. Furthermore, the presence of large quantities of IL-1b in the urine of Asc - / - and Nlrp3 - / - mice demonstrated that pro-IL-1b is processed in these mice. Yet, effects of caspase inhibition were limited, suggesting that additional mechanisms must be involved.
- MMP-7 Proteolytic cleavage by MMP-7 was identified as a new mechanism of IL-1b processing and evidence for IL-1b fragmentation by MMP-7 was obtained by direct cleavage of the purified components, in vitro.
- MMP-7 has metalloendopeptidase activity and is known to degrade collagen, proteoglycans, fibronectin, elastin and casein.
- MMP7 is activated following TNF-a or IL-1b stimulation of cells. It is commonly expressed in epithelial cells and has been shown to regulate the activity of defensins in the intestinal mucosa.
- Mmp7 was identified as the most strongly activated gene in pathological bladders and the protein was mainly expressed in the bladder epithelium.
- Kidney pathology is controlled, to a large extent by TLR4 (7, 8), acting upstream of the IRF-3 and AP-1 transcription factors. Kidneys of Tlr4 - / - mice therefore fail to respond to most UPEC strains and develop ABU. In contrast, a residual response was present in the bladders of Tlr4 - / - mice, through MyD88 and NF-kB signaling, Il1b and Tnf expression, potentially suggesting a mechanism for the increased expression of IL-1b and IL-1b-dependent genes.
- MMP-7 Inhibition of MMP-7 was also protective, but with a less complete phenotype than mice receiving the IL-1RA.
- IL-1RA As IL-1RA is in clinical use, testing immunotherapy with drugs like Anakinra as an adjunct to antibiotics may be a realistic option in acute cystitis patients.
- Patients with acute cystitis were enrolled at two primary care clinics.
- a diagnosis of acute cystitis was based on a urine dipstick analysis positive for bacteria and symptoms from the lower urinary tract, including frequency, dysuria and suprapubic pain.
- Midstream urine specimens were obtained at the time of diagnosis.
- E . coli 83972 bacteriuria was established by intravesical inoculation (10 5 CFU/ml in saline), daily for three days and the outcome was measured as the total number of UTIs during an optimal period of 12 months followed by a cross over to a similar period without E . coli 83972 bacteriuria.
- Urine samples were obtained for cytokine analysis during E . coli 83972 bacteriuria and symptom scores were registered.

- the uropathogenic E . coli (UPEC) strain CFT073 and the asymptomatic bacteriuria strain E . coli 83972 (ABU) were used as controls.
- Cells were infected with 10 8 CFU/ml for 4 hours with gentamicin added after 1 hour, to focus on the early host response.
- Supernatants were collected for analysis in which inflammatory mediators in cell supernatants were quantified.
- IL-1 ⁇ secretion was detected following infection with the acute cystitis (CY) strains CY-17, CY-92 and CY-132.
- E. coli CFT073 also triggered IL-1 ⁇ secretion.
- the response to the ABU strain E. coli 83972 was low ( P ⁇ 0.005 compared to uninfected cells), indicating a possible virulence-association ( Figure 1A ).
- Pro-IL-1 ⁇ and mature IL-1 ⁇ were detected by Western blot analysis of the supernatants ( Fig 1B ), suggesting that the acute cystitis strains activate de novo IL-1 ⁇ synthesis and IL-1 ⁇ processing.
- the IL-1 ⁇ response was also shown to differ among the CY strains tested, with a low response to CY-49 ( Fig 1A and 1B ).
- IL-1 ⁇ activation is a characteristic of acute cystitis strains
- we infected human bladder epithelial cells with an epidemiologically defined collection of paediatric acute cystitis isolates ( n 67). The majority of these strains (85 %) triggered an IL-1 ⁇ response > 5 pg/ml and 64 % of those triggered a high response (40 - 1,000 pg/ml, Fig 1C ).
- pro-IL-1 ⁇ As pro-IL-1 ⁇ is processed by the inflammasome, we examined if infection triggers an inflammasome response in human bladder epithelial cells. By confocal microscopy, we visualized the infection-induced changes in ASC (Apoptosis-associated speck-like protein containing a CARD), NLRP-3 (NACHT, LRR and PYD domains-containing protein 3), Caspase-1 and IL-1 ⁇ levels ( Fig 1D ). Inflammasome protein levels increased after infection with CY-92, CY-17, CY-132 and CFT073 but the ABU strain had no effect, consistent with the low IL-1 ⁇ .
- ASC Apoptosis-associated speck-like protein containing a CARD
- NLRP-3 NACHT, LRR and PYD domains-containing protein 3
- Caspase-1 and IL-1 ⁇ levels Fig 1D .
- Inflammasome protein levels increased after infection with CY-92, CY-17,
- mice were infected by intravesical inoculation with acute cystitis strains that triggered high IL-1 ⁇ responses in human bladder epithelial cells, in vitro (CY-17 or CY-92) or with CFT073.
- Bladder infection was evaluated at sacrifice after 7 days ( Fig 2A ) and the kinetics of infection were followed in urine samples obtained after 6 and 24 hours, 3 and 7 days ( Fig 2B ).
- Infected bladders showed macroscopic evidence of moderate inflammation, with an increase in size, edema and hyperaemia. Tissue pathology was confirmed by histology, with a loss of structure in infected mice, compared to uninfected controls ( Fig 2A ). Tissue inflammation was accompanied by an increase in urine neutrophil numbers and bacterial numbers reached a peak after 24 hours and then declined ( Fig 2B ). Bacteria and neutrophils were detected by immunohistochemistry in the bladder mucosa of infected mice ( Fig 2A ) and a rapid IL-1 ⁇ response, as confirmed by mucosal staining for IL-1 ⁇ after 24 hours and elevated IL-1 ⁇ levels in urine.
- mice To inactivate the inflammasome-dependent processing of IL-1 ⁇ , subsequently infected NLRP-3 ( Nlrp3 - / - ), ASC ( Asc - / - ) or Caspase-1 ( Casp1 - / - ) deficient mice, as described above. C57BL/6 WT mice were included as controls. Major, genotype-specific differences in bladder pathology were detected after seven days ( Fig 2C and 2D ). Bladders from Asc - / - and Nlrp3 - / - mice were severely inflamed and enlarged with edema, hyperaemia and thickened bladder walls.
- Bladder pathology was accompanied by high bacterial 170 counts in urine and bladder tissue ( FIG 2C ).
- Asc - / - mice the neutrophil influx accelerated until day 7, indicating a loss of homeostatic control and progression to chronic inflammation.
- Infiltrating bacteria and neutrophil aggregates or micro-abscesses were detected in the mucosa of Asc - / - and Nlrp3 - / - mice, with extensive sloughing of epithelial cells into the lumen ( Fig 2D ).
- Infection was accompanied by strong epithelial IL-1 ⁇ staining in bladder tissue sections after 24 hours and elevated urine IL-1 ⁇ levels. This hyper-inflammatory phenotype was recreated in Asc - / - mice after infection with the acute cystitis strains CY-92 and CY-17, which triggered high IL-1 ⁇ responses in vitro.
- mice lacking functional ASC or NLRP-3 developed a hyper-inflammatory state with extensive tissue damage. This gives rise to the therapeutic use of these proteins in the prevention or treatment of cystitis.
- RNA was subjected to genome-wide transcriptomic analysis. Regulated genes were defined in comparison with RNA from uninfected bladders of each genetic background (fold change (FC) > 1.41, and P ⁇ 0.05, Figure 3 ).
- Innate immune regulators were moderately enhanced, such as the NF-KB constituents, Myd88, Mapk11 and chemokines Ccl -7, -5 and -2 (FC about 2). Importantly, inflammasome gene expression was virtually absent in Il1b - / - mice further emphasizing the key role of IL-1 ⁇ for bladder pathology.
- IL-1 ⁇ dependent genes confirmed the over-activation of IL-1 ⁇ dependent gene expression in Asc - / - and Nlrp3 - / - mice.
- the IL-1 ⁇ dependent signaling cascade was completely abrogated, suggesting a lack of alternative activation mechanisms.
- IL-1 ⁇ -independent activated genes included the transcription factor Irf3 , which controls the innate immune response to kidney infection and is activated via TLR4, TICAM-1 (TRIF) and TICAM-2 (TRAM) rather than the MyD88 and NF-KB pathway (7).
- IL-1 ⁇ processing was further examined in human bladder epithelial cells infected with acute cystitis strains CY-17, CY-132 and CY-49, which generated the strongest IL-1 ⁇ response in the epidemiological survey (10 5 CFU/ml, 4h). CFT073 and ABU were included as positive and negative controls.
- MMP-7 matrix metalloproteinase
- MMP-7 activation was detected as early as 24 hours after infection but MMP-7 was not regulated in resistant mice (Il-1b -/- or Casp1 - / - mice) ( Fig 4C) at 7 days. Increased Il1b and Mmp7 mRNA levels were confirmed by RT-PCR, in these tissues compared to WT mice.
- MMP-7 was subsequently shown to cleave or degrade IL-1 ⁇ , in vitro.
- GST-tagged recombinant IL-1 ⁇ was incubated with purified MMP-7 and proteolytic fragments were identified by Western blots using IL-1 ⁇ specific antibodies ( Figure 4D ).
- Kinetic analysis showed a time-dependent cleavage of IL-1b with a gradual reduction in full-length protein from 10 to 60 minutes. After 24 hours, IL-1 ⁇ was completely degraded by MMP-7 ( Fig 4D ). Time-dependent ASC degradation by MMP-7 was also detected but NLRP-3 was not affected.
- the IL-1 ⁇ degradation products corresponded approximately to pro-IL-1 ⁇ (36kDa), the N-terminal fragment (29 kDa) and mature IL-1 ⁇ (16-18 kDa), also seen in supernatant from cells infected with CY-92. Addition bands were also detected after MMP-7 degradation ( Fig 4D ). NLRp-3 was not degraded and therefore serves as a negative control for ASC degradation by MMP-7.
- Mmp7- / - mice were infected with CFT073. No disease phenotype was detected ( FIG 4E ) and Il1b and IL-1 ⁇ - dependent gene expression was comparable to WT mice ( Fig 3 ).
- Activated genes were involved in IRF1-dependent IL-1 signaling, including Birc3, Myd88, Irf1 and Ccl5.
- a moderate IL-1 ⁇ response was observed in these mice, with submucosal 1L-1 ⁇ staining and moderate mucosal accumulation ( Fig 4F ).
- IL-1 ⁇ levels in urine were comparable to those of WT and Casp1 - / - mice ( Fig 4F ).
- NLRP-3 and ASC act as negative regulators of MMP7 expression
- ASC and/or NLRP-3 may act as negative regulators of MMP7 expression.
- ASC or NLRP-3 expression was inhibited by transfection of human bladder epithelial cells with ASC- or NLRP3- specific siRNAs and the effects on MMP-7 expression were quantified by confocal imaging and Western blots.
- MMP-7 expression increased drastically in transfected and infected cells where the expression of ASC or NLRP-3 had been inhibited ( Figs 5A and 5B ).
- ASC was shown to pull down NLRP-3 in nuclear extracts of uninfected cells but after infection, a reduction in ASC/NLRP-3 interaction was detected suggesting that a loss of ASC/NLRP-3 interaction in the nuclear compartment accompanies MMP7 activation.
- DNA fragments spanning the entire promoter were used as probes in electrophoretic mobility shift assays (EMSA).
- a DNA fragment of 259 bp, adjacent to the transcription start site (P1,position -18/-276) was shown to interact with a nuclear protein extract from infected bladder cells, resulting in a significant band shift ( Figs 5C and 5D ).
- Specificity for ASC and NLRP-3 was confirmed by competition with specific antibodies ( Fig 5D ).
- the probe formed a single low molecular weight 256 band, serving as a negative control.
- ASC binds directly to the MMP7 promoter
- recombinant ASC protein was incubated with the 259 bp DNA sequence and examined by EMSA. Strong dose-dependent binding of ASC to MMP7 promoter DNA was detected as a band shift, which was competitively inhibited by specific antibodies ( Fig 5E ).
- NLRP-3 and ASC act as negative regulators of MMP7 expression and identify an ASC binding site in MMP7 promoter DNA, adjacent to the transcription start site.
- mice were also treated with an MMP inhibitor (Batimastat), (0.5 mg in 100 ⁇ l of PBS i.p. 30 minutes before, first three and last three days of infection, Figure 6A ).
- MMP inhibitor 0.5 mg in 100 ⁇ l of PBS i.p. 30 minutes before, first three and last three days of infection, Figure 6A .
- Treated mice were protected against macroscopic bladder pathology ( Figure 6B ) with a reduction in the bladder edema and hyperemia compared to untreated Asc - / - mice ( Figure 6C ).
- Neutrophil infiltration was markedly reduced ( Figure 6D ).
- mice treated with IL-1RA showed a loss of mature IL-1 ⁇ in urine and mice treated with the MMP inhibitor showed defective processing of IL-1 ⁇ .
- urine samples were obtained from patient with acute cystitis at the time of diagnosis.
- results show that patients with acute cystitis have elevated concentrations of IL-1 ⁇ and MMP-7 in urine, identifying IL-1 ⁇ and MMP-7 as biomarkers of acute cystitis.
- Irf3 - / - mice were used as positive controls for kidney pathology. After infection, their kidneys were severely inflamed, with macroscopic abscesses. Bacterial counts and neutrophil numbers were elevated compared to WT mice. Neutrophil infiltration and bacterial invasion was detected in the mucosa and collecting ducts. There was, however, no evidence of bladder pathology in lrf3 - / - mice. NLRP-3 and ASC staining resembled that in WT mice and the IL-1 ⁇ response was weak.
